It’s 1979 All Over Again

May 2, 2008 · No Comments

With only a few minor adjustments to account for dates and sports utility vehicles, this NY Times article on recent car buying trends could have been written thirty years ago. Start with the headline:

As Gas Costs Soar, Buyers Flock to Small Cars

I have childhood memories of such headlines. Change the price-a-gallon and replace “sport utility vehicles” with “gas-guzzling boat-sized sedans” and the following paragraph would have been relevant back then, too:

The switch to smaller, more fuel-efficient vehicles has been building in recent years, but has accelerated recently with the advent of $3.50-a-gallon gas. At the same time, sales of pickup trucks and large sport utility vehicles have dropped sharply.

Finally, here is where history repeats itself in perhaps the most moronic way:

The trend toward smaller and lighter vehicles with better mileage is a blow to Detroit automakers, which offer fewer such models than Asian carmakers like Toyota and Honda.

Yet as a testament to how the entire auto industry, regardless of country of origin (which means little in a globalized production line), is completely behind the times, consider the gas mileage of the fuel-efficient vehicles the Times lists in a sidebar:

The city mileage does not even reach 30 M.P.G.! We should be getting 100 M.P.G. now. We should have taken care of this thirty years ago. But no-o-o-o-o. We got frightened by the Iranian Revolution and elected an ex-B movie actor who stroked our precious imperialist egos (”It’s okay, my fellow Americans, we’re still a great big superpower”), and, once in office, undid the energy policies of the Carter Admin that would have saved us time, money, war, lives, and at least a part of the global warming crisis we face. Thanks, Reagan Democrats! I hope you guys learn your lesson this time!

But, like Detroit, you probably won’t.

A Future of Floods and Droughts

February 2, 2008 · No Comments

According to a recent scientific study, as reported in Science Daily, the water crisis in the Western United States is the result of human-induced climate change and will continue to get worse at current levels of global warming.

The team scaled down global climate models to the regional scale and compared the results to observations over the last 50 years. The results were solid, giving the team confidence that they could use the same models to predict the effects of the global scale increase in greenhouse gases on the Western United States in the future.
The projected consequences are bleak.
By 2040, most of the snowpack in the Sierras and Colorado Rockies would melt by April 1 of each year because of rising air temperatures. The earlier snow melt would lead to a shift in river flows.
The shift could lead to flooding in California’s Central Valley. Currently, state reservoirs are filled during the rainy season. As the water is drawn down, the reservoirs are replenished with snow melt from the Sierras.
If that snow melts earlier, as predicted in the climate models, the reservoirs could overflow.
“We are headed for a water crisis in the Western United States that has already started,” Barnett said. “A couple of decades ahead, we might not have that snowpack, making us more susceptible to flooding.”

The illustration accompanying the article juxtaposes aerial photos of South Cascade Glacier, Washington, making the case with stark visual contrast.
